Abstract

The ZnO-TiO2 films were co-sensitized with single, double, and triple natural dyes, leading to distinct effects on the optical properties. ZnO (wurtzite) and TiO2 (anatase) were prepared from commercial powders and the XRD results revealed that the crystallite size is 158 and 443 nm, respectively. The UV absorbance of ZnO powder shows significant peaks at wavelengths of 255 and 345 nm, with a band gap energy of 3.07 eV. Meanwhile, TiO2 powder exhibits a maximum peak at 325 nm and possesses a band gap energy of 3.16 eV. The extraction of natural dyes (Moringa oleifera, Biancaea sappan, Matricaria chamomilla, Rosa, and Chrysanthemum) was carried out using a cost-effective and simple method involving immersion in ethanol for 2 × 24 h followed by filtration. FTIR test results show the presence of O–H, C–H, C=C, and C–O functional groups. The results of coating the ZnO-TiO2 film with natural dyes show that the UV spectrum peaks are higher than the visible light wavelength. Co-sensitization of double natural dyes demonstrated different effects on the ZnO-TiO2 film, i.e., achieved panchromatic absorption mainly in the UV wavelength spectrum.

Abstract

Zn-doped magnesium titanate powders with different Zn compositions, x = 0 to 1, were synthesized using the dissolved metals mixing method. The roles of calcination temperature and dopant Zn composition on powder morphology, phase composition, crystallite size, crystalline cell volume, and local environment were investigated through scanning electron microscope (SEM) observation, Rietveld analysis of powder X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and X-ray absorption spectroscopy (XAS) for Ti K-edge X-ray absorption near edge structures (XANES). We found that the geikielite solid solutions were formed during the pre-calcination at 400 °C for 1 h. Results show spherical particles (~1 µm) with minimal size variation across calcination temperatures (600–800 °C) and Zn compositions, though some agglomeration occurs. After calcination at 600 °C for 4 h, the crystalline cell volume of geikielite was proportional to the Zn composition, implying the formation of the solid solution in the range of Zn composition up to the level close to x = 1. This successful synthesis of the Zn-doped magnesium titanate nanocrystals at temperatures much lower than those required by the solid-state reaction method was thereby well demonstrated.

Abstract

Problems that generally affect the level of anxiety of parents whose preschoolers undergo hospitalization are divided into two objects, internal factors including: (1) Age factors owned by parents; (2) Sex differences of parents; and (3) Traumatic fears felt by parents. While from the external include: (1) The level of education of parents is quite low; and (2) Parents' knowledge of children's health is still low. One indicator in lowering the anxiety level of the patient's parents is therapeutic communication skills. In general, the purpose of this study was to determine the relationship between nurses' therapeutic communication with the level of parental anxiety due to hospitalization in preschool-aged children at Ranap Lima Mitra Plumbon Hospital. This study uses quantitative research with a cross-sectional approach and uses correlation or correlational research methods. The population in this study was all parents of patients whose preschool-aged children underwent hospitalization in Ranap Room Five of Mitra Plumbon Hospital. The sampling technique uses accidental sampling method based on chance. In terms of this sampling, researchers conducted a study for one month, where the sample obtained was 28 respondents.

Abstract

Extraction and study of the optical properties of natural dyes from several plant parts such as leaves, flowers, tubers, and fruits have been carried out using a simple maceration method and UV-Vis absorption characterization. The samples were divided into several groups in this study, namely the flower group (Tagetes sp., Paeonia sp., Centaure sp., Chrysanthemum sp., Carthamus tinctorius, Gomphrena globosa, Myosotis sylvatica, Lavandula sp., Clitoria ternatea, Matricaria chamomilla, Hibiscus sabdariffa, and Rosa sp.); the leaf group (Mangifera indica, Moringa oleifera, Graptophyllum pictum, Spinacia oleracea, Citrus hystrix, and Terminalia sp.); and the tuber and fruit group (Solanum lycopersicum, Cucurbita moschata, Garcinia mangostana, Curcuma longa, Beta vulgaris, and Caessapina sp.).  The extract of natural dyes was successfully produced using a low-cost and simple extraction approach via dehydration, immersion for 2×24 hours in ethanol, and followed by filtration. The optical properties of the dyes in UV and visible light range were observed using a UV-Vis spectrophotometer in the wavelength of 400-700 nm. The absorption behaviour showed dominant peaks at different wavelengths for each group. Potentially, to do a combination of dyes (co-sensitization: using more than a dye with different absorption spectra to achieve a panchromatic response) to widen the wavelength absorption for dye-sensitized solar cell (DSSC) applications.

Based on the results of observations by the community service team, in recent years, Batik Shaho producers have switched from natural to synthetic dyes such as remasol and naphtol for efficiency, even though these materials are genotoxic, carcinogenic, and classified as B3 waste. The purpose of this community service is to carry the concept of sustainable assistance by providing new understanding and skills for Batik Shaho partners in using a photocatalytic degrader for batik fabric dye waste. This assistance focuses on training and socialization of the use of a batik fabric dye degrader which is expected to help craftsmen in handling dye waste. Considering that the efficiency of waste handling in partner areas is still limited, the ITK community service team proposed the dissemination of decolorizer technology. This tool is equipped with a real-time degradation sensor, high-performance TiO₂ active material, and UV lamps to support the dye waste decolorization process. This system is designed to be integrated and is expected to have a significant impact on dye waste management. This initiative is part of a real effort to realize the Environmental Care Movement through the application of environmentally friendly and sustainable technology. The indicator of the success of this activity is proven through the collection of data from 25 training participant respondents. Based on the results of the questionnaire evaluation, more than 90% of participants achieved an average score above 80. This indicates the effectiveness of the training held in improving the competence and knowledge of participants, especially related to the management of fabric color waste using photocatalytic technology.

Abstract

his study aims to describe the use of musicalization videos as a medium for formative assessment in poetry writing instruction for seventh-grade students at SMP Negeri 4 Kota Cirebon. Using a qualitative approach with a descriptive method, the study involved students in the creation of free-form poems, which were then developed into musicalization videos and uploaded to social media as a form of formative evaluation. The results show that this instructional strategy enhances students’ creativity, participation, and understanding of poetry. Adapting the learning process to students’ learning styles—visual, auditory, and kinesthetic—helped them express ideas, refine word choices, and integrate poetry with musical elements. Furthermore, the activity also improved students’ self-confidence, collaboration skills, and digital literacy. Thus, the use of musicalization videos as formative assessment has proven effective in developing poetry writing skills and enriching the literary learning experience in a contextual and enjoyable way.
